Adjustable superconducting anisotropy in MoGe-permalloy hybrids.

We studied the magneto-transport properties of magnetically coupled superconductor ferromagnet MoGe/Permalloy bilayers. The rotatable anisotropy Permalloy ferromagnet with stripe domain structure induces in-plane anisotropy in superconducting order parameter. Superconducting phase diagram shows that near the superconductor-normal state phase boundary the superconductivity is localized in narrow mesoscopic channels just above the magnetic domain walls. By changing the in-plane direction of magnetic stripe domains it is possible to re-configure the direction of the superconducting channels and controllably rotate the direction of the in-plane anisotropy axis in the superconductor.
